Phys. Rev. Lett. 73, 189–192 (1994)Magnetic structure of the spin-liquid state in a frustrated pyrochloreReceived 10 February 1994; published in the issue dated 4 July 1994 The antiferromagnetic pyrochlores exhibit a high degree of frustration, resulting in a continuously disordered ground state. Neutron powder diffraction experiments have detected magnetic scattering similar in form to a liquid structure factor. We present a single crystal neutron scattering study of the pyrochlore CsNiCrF6 and quantify the anisotropy of the scattering. Using these data, we show that there are strong correlations between nearest-neighbor spins, and no significant longer correlations. This provides clear evidence for the liquidlike nature of the pyrochlore magnetic structure. © 1994 The American Physical Society URL:
